Such compositions are particularly suitable for use as rinsable or non-rinsable products for washing and conditioning hair, hair setting, or hair styling.

This application is a National Stage application under 35 U.S.C. § 371,of International application PCT/FR96/01435, filed Sep. 16, 1996.

The present invention relates to a cosmetic or dermatologicalcomposition for treating keratin substances, in particular the hair,comprising at least one grafted silicone polymer containing apolysiloxane skeleton grafted with non-silicone organic monomers, and atleast one silicone chosen from silicones containing at least onequaternized or non-quaternized amine function, silicone resins andsilicone gums.

Polymers containing a polysiloxane skeleton grafted with non-siliconeorganic monomers are known in the prior art and are preferably chosenfrom those described in patent applications EP-A-0,582,152 and WO93/23009. They are used in particular in hair compositions for theirstyling properties.

The Applicant has discovered, surprisingly, that by combining at leastone silicone polymer containing a polysiloxane skeleton grafted withnon-silicone organic monomers, with at least one silicone gum and/or asilicone resin and/or a silicone containing at least one quaternized ornon-quaternized amine function, an improvement in the volume and in thebody of the hairstyle is obtained while at the same time having betterstyling and/or holding properties such as the fixing power. The hair is“lighter” and styles easily.

The feel and softness properties of the hair are also improved.

The term fixing power of the composition will be understood to denotethe ability of this composition to give the hair cohesion such that theinitial shape of the hairstyle is held.

The composition according to the invention is thus essentiallycharacterized in that it comprises, in a cosmetically ordermatologically acceptable medium, at least one grafted siliconepolymer containing a polysiloxane skeleton grafted with non-siliconeorganic monomers, and at least one silicone chosen from siliconescontaining at least one quaternized or non-quaternized amine function,silicone resins and silicone gums.

In the following text, in accordance with what is generally accepted,the term silicone polymer is understood to denote any organosiliconpolymer or oligomer having a linear or cyclic, branched or crosslinkedstructure, of variable molecular weight, obtained by polymerizationand/or polycondensation of suitably functionalized silanes, andconsisting essentially of a repetition of main units in which thesilicon atoms are linked together by oxygen atoms (siloxane bonding≡Si—O—Si≡), optionally substituted hydrocarbon radicals being linkeddirectly via a carbon atom to the said silicon atoms. The most commonhydrocarbon radicals are alkyl radicals, especially C₁-C₁₀ alkylradicals, and in particular methyl, fluoroalkyl radicals, aryl radicalsand in particular phenyl, and alkenyl radicals and in particular vinyl;other types of radicals which can be linked, either directly or via ahydrocarbon radical, to the siloxane chain are, especially, hydrogen,halogens and in particular chlorine, bromine or fluorine, thiols, alkoxyradicals, polyoxyalkylene (or polyether) radicals and in particularpolyoxyethylene and/or polyoxypropylene, hydroxyl or hydroxyalkylradicals, substituted or unsubstituted amine groups, amide groups,acyloxy radicals or acyloxyalkyl radicals, hydroxyalkylamino oraminoalkyl radicals, quaternary ammonium groups, amphoteric or betainegroups, anionic groups such as carboxylates, thioglycolates,sulphosuccinates, thiosulphates, phosphates and sulphates, needless tosay this list not being limiting in any way (so-called “organomodified”silicones).
